萼

Sepals ovate-oblong, as long as corolla tube, hirsute.

萼片卵形长圆形，倍于花冠筒，具粗毛。

Calyx lobes linear, 1.2-1.6 cm, to 3 cm in fruit, densely pale yellow hirsute on both sides, apex subacute.

线形的萼裂片，1.2-1.6厘米，在3厘米在果期，浅黄具粗毛两面，近尖的先端的浓密。

Follicles pubescent or hirsute; sepals erect in fruit.

蓇葖果短柔毛或具粗毛；在果期的萼片直立。

The results showed that in nitrogen pollution water, the repair results of Eichhornia crassipes is better than Hosta ventricosa.

结果表明凤眼莲对氮污染水体的修复效果要好于紫萼玉簪。

In alltreatments, the removal of nitrogen and the accumulation in vivo of nitrogen in Eichharniacrassipes are greater than Hosta ventricosa.

在各处理中凤眼莲对氮的去除率以及体内氮的累积量都要大于紫萼玉簪。

Comparing two Cd-accumulating plants the Eichhornia crassipes accumulating ability is 5-7 times of Hosta ventricosa.

从这两种植物富集镉能力的比较来看，凤眼莲对镉的富集能力是紫萼玉簪的5～7倍。

Both of Eichharnia crassipes and Hosta ventricosa can grow normally in a single nitrogenand phosphorus stress condition, The higher the concentration of nitrogen and phosphorus in waterthe higher the chlorophyll content and dry matter content in plants, it means the growth of plants isgood, This proves that Eichhamia crassipes and Hosta ventricosa has a very strong ability to adaptin a single nitrogen and phosphorus pollution water, they can be used for repairing a singlenitrogen and phosphorus pollution water.

在单氮和单磷胁迫条件下植物都能够正常生长，并且水体中氮、磷浓度越高凤眼莲和紫萼玉簪体内的叶绿素含量及干物质含量就越高，说明两种植物的生长状况就越好，这一点证明两种植物对氮、磷污染的适应能力都很强，可以用于修复单氮和单磷污染水体。

Hosta ventricosa in control group grew ordinarily. The diameter of can reach 2 cm. The plants were vertical and straight. The main roots have a lot of fibrous roots. They were white. The leaves were green. 80% of the plants flowered in July.

空白组的紫萼玉簪在整个实验期内生长正常，根状茎粗达2厘米，植株直生，主根密生多数细长须根，呈白色；叶片绿色，在7月时80％的植物开花。

Sepals 5, valvate or slightly imbricate, usually slightly shorter than hypanthium.

萼片5，覆瓦状的镊合状的或稍，通常稍短于托杯。

Shrubs 0.2–1 m tall; sepals shorter than hypanthium; drupe ca.

灌木0.2-1米高；萼片短于托杯；核果的约1厘米 9 C。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
